(Cl. 49-434) ABSTRACT 0FTHE DISCLOSURE For use in a double sash window installation including alongitudinally vertically grooved wooden side jamb and a Weatherstriphaving a longitudinally vertically extending grooved backa smallclip-like key adapted to be fitted in the corresponding confrontinglyarranged grooves of the side jamb and Weatherstrip member and fixedlysecured in the uuderportion of the head jamb of the window frame forsecuring the Weatherstrip member in the window frame.

This invention relates to a double sash window installation including awood window frame and an opposingly arranged pair of Weatherstripmembers. More specifically, the invention relates to a substantiallysmall clip-like key member for securing a Weatherstrip member to awindow frame.

The typical wooden window frame is rectangular and includes oppositelyarranged vertically extending side jamb members and a horizontal headjamb member fixedly bridged across the upper ends of the side jambmembers. Each side jamb member is provided with a longitudinallyextending grooveway along the inward side. In certain windowinstallations a long narrow wooden parting strip is fixed in thegrooveway and serves as guide means between the upper and lower windowsashes. In other window installations, a pair of sheet metalweatherstrip members or a pair of Weatherstrip and balance assembliesare used to operatively secure the window sashes. In prior art windowinstallations using weatherstrip or Weatherstrip sash balance assembliesthe grooves in the side jam members of the Window frame are not used andthe Weatherstrip member or Weatherstrip jamb assemblies are fixedlysecured to a respective jamb member by stapling, nailing or the like.The typical wood window frame therefore serves as a combination sort offrame which can optionally be used in the cheaper window installationemploying a wood parting strip or in a more expensive installationemploying Weatherstrip members or Weatherstrip and sash jamb assemblies.

The present invention concerns the window installation employingWeatherstrip members or Weatherstrip and sash balance assemblies. Forthe stake of clarity, in this specification the invention will bedescribed as being in a window installation employing Weatherstripmembers; it is apparent, however, that the invention is equallyapplicable in an installation including weatherstrip and sash balanceassemblies.

The general object of the present invention is to provide asubstantially simple and fast way for attaching a Weatherstrip member toa respective window frame side jamb without nailing, stapling oremploying other such costly means.

A further object is to provide a substantially small clip-like keymember of one-piece sheet-metal form which is economical to make andeasy to install.

A further object is to provide an interlocking key member interengagingthe respective grooveway portions of the Weatherstrip member and Windowframe side jamb member and for preventing relative lateral displacementof the members.

ice

A further object is to provide a side jamb-Weatherstrip interlocking keymember including barb-like cleat means securable in the window framehead jamb member for additionally securing the Weatherstrip member.

The means by which the foregoing and other objects of the presentinvention are accomplished and the manner of their accomplishment willbe readily understood with reference to the accompanying drawings inwhich:

FIG. 1 is a view of a double sash window installation and such windowstructure including the interlocking key on the line V-V of FIG. 1.

FIG. 2 is a perspective view of the interlocking key member.

FIG. 3 is a perspective view of the interlocking key member as installedand interengaging the Weatherstrip and side jamb members (partly shown)and with the Window frame head jamb member removed.

FIG. 4 is a vertical plane sectional view taken as on the line IVIV ofFIG. 1, but with the upper window sash slightly lowered.

FIG. 5 is a horizontal plane sectional view taken as on the line VV ofFIG. 1.

FIG. 6 is a prior art horizontal plane sectional view taken as along asection corresponding to FIG. 5 and illustrating the attachment of theWeatherstrip member with nails. In the prior art view the window frameside jamb member is indicated by letter A, the upper sash member byletter B, the Weatherstrip member by letter C and the nails attachingthe Weatherstrip member by letter D.

The window installation is indicated by numeral 11 in FIG. 1 andillustrates upper and lower window sashes 13, 15 slidably securedrespectively in opposingly arranged weatherstrip members 17, 19. Asubstantially rectangular window frame 21 having right and left sidejamb members 23, 25 and a head jamb member 27, frames the window sashesand with Weatherstrip members 17, 19 respectively arranged along sidejamb members 23, 25.

Since the right and left components of window installation 11 aresubstantially alike, the inventive structure will be described inconjunction with the right side components, it being apparent that theleft side components of the window installation are similarly arranged.

FIGS. 3, 4 and 5 illustrate the interlocking key means of the presentinvention in conjunction with the window frame side jamb and head jambmembers, 23, 27 respectively; Weatherstrip member 17; and upper sashmember 13. The longitudinally extending grooved portions respectively ofside jamb member 23 and weatherstrip member 17 are confrontingly matchedand define a vertically extending enclosed area 29 terminated at theupper end by head jamb member 27. Thus, the longitudinal groovedportions 31, 33 respectively of side jamb member 23 and Weatherstripmember 17 are confrontingly arranged and define the vertically extendingenclosed area 29. An interlocking key member 35, comprising theprincipal element of the invention, forms the interlocking structurebetween side jamb member 23 and Weatherstrip member 17.

Interlocking key member 35 is preferably of one-piece sheet-metal formand includes basically a body part 37 and a pair of cleat parts 39, 39'.Body part 37 is elongated and substantially U-shaped cross-sectionallyand includes an intermediate portion 41 and a pair of parallel arrangedside portions 43, 43' (see FIG. 2). Cleat parts 39, 39' includerespectively base portions 45, 45' and barb portions 47, 47'. It will beunderstood that barb portions 47,

47 may be omitted without departing from the spirit and scope of thepresent invention. Cleat parts 39, 39' are integrally securedrespectively to the distal upper portion of respective side portions 43,43' of body part 37 with the respective base portions 45, 45 beingsubstantially co-planar. Barb portions 47, 47 project respectivelyupwardly and are integrally secured respectively to base portions 45,45'; barb portions 47, 47' preferably are in the form of right angularprojections struck from the respective base portions 45, 45.

The body part of interlocking key 35 preferably is of suchcross-sectional proportions as to snugly fit enclosed area 29. Keymember 35 is arranged with the oppositely extending cleat parts 39, 39projecting perpendicularly outwardly respectively from parallel wallportions 49, 49' of Weatherstrip member groove portion 33. Horizontallyextending base portions 45, 45' of cleat parts 39, 39' rest on or arecontiguous with the upper edge surface 51 of Weatherstrip member grooveportion 33 when the key member is being inserted, as will be betterunderstood in the description of the installation to follow hereinafter,but is held upwardly away from the edge surface of the Weatherstrip bythe barb portions 47, 47 when the installation is completed as shown inFIG. 4. Interlocking key member 35 is arranged with the upper surfacesrespectively of cleat parts 39, 39' in flat face-toface engagement withthe under surface 53 of head jamb member 27 and with the respective barbportions 47, 47' secured in the under portion of the head jamb memher(see FIG. 4). The oppositely facing flat surfaces 55, 55 of body partside portions 43, 43' respectively engage the parallel groove-wallsurfaces of side jamb groove portion 31 and the parallel groove-wallsurfaces of Weatherstrip groove portion 33, and prevent relative lateraldisplacement of the side jamb member and Weatherstrip member.

Interlocking key member 35 may be installed in window installation 11 inthe following manner: both upper and lower sashes 13, 15 are movedrespectively to fully lowered positions; the upper portion ofWeatherstrip member 17 is sprung outwardly away from window frame sidejamb member 23; interlocking key member 35 is inserted in Weatherstripgroove portion 33 with the respective cleat parts 39, 39 projectingrespectively outwardly from the groove portion and resting on the upperedge 51; the Weatherstrip member is moved outwardly against the sidejamb member and until the intermediate portion 41 of locking key memberbody part 37 engages the bottom surface of the side jamb membergrooveway. It will be understood that there is a slight space betweenthe upper edge of the Weatherstrip member 17 and head jamb member 27,which space is greater than the height of barbs 47, 47 so thattheabove-mentioned outward movement is possible. The upper and lower sashes13, 15 are then separately raised, to forcefully strike the respectivecleat parts 39, 39' which moves the key member upwardly and sets therespective barb portions 47, 47 in head jamb member 27.

The interlocking key means of the present invention provides asubstantially simple and fast way to attach a Weatherstrip member to awindow frame without nailing, stapling or other such costly fasteningmeans. The key member of the present invention is of one-piececonstruction and is economical to make and easy to install. In summary,the present invention provides a very practical side jamb-Weatherstripinterlocking key means.

Although the present invention has been described with reference to apreferred embodiment, it is to be understood that it is not to be solimited since changes and modifications may be made therein which arewithin the full intended scope of this invention as hereinafter claimed.
